On this bed frame are two M, in which it can freely turn, and having a 35 parallel rails B, B, substantially parallel with pulley M, secured to it, for driving the same. the front of themachine, on which is arranged In the end of this shaft M, is a long twist bit to slide forward and backward by its under or drill P, which extends freely through a grooves a, acarriage frame 0, and on the upsocket or hole h, in a bar m, of a frame it, per side of this frame O are two parallel rails adapted to slide back and forth byits bottom 40 D, D, at right angles to the longitudinal rails portion in side grooves in the bed frame A, 0 B on which rails D is adapted to slide back see Fig. 7.

F is an arm of rock shaft G arranged to turn in bearings u and extending to the front. having a handle arm H for operation of the same, the arm F having a forked end '0 which engages with a pin secured to the sliding frame C. Moving the handle arm H in the direction of the arrow 00' Fig. 1, the frame 0 is caused to move to the right, see dotted lines Fig. 4, and moved back again by swinging the handle in the opposite direction.

Secured to the upper side of the upper frame are two cross bars J each having two upright lugs y through each of which are thumb screws a for operation of the same, their inner ends being pointed. Between the ends of these screws a is placed and secured the boot tree leg K as shown more particularly in Fig. 2, for operation thereon, and it is placed in position at the required height, as to its proper distance from the left hand for the operation of the machine upon the same, as well as horizontally and when so placed the screws a are turned against the tree leg which by their pointed ends firmly 25 The carriageframe G,; is 'firstcme ":againstiitsstopfwhichhasheenpreviouslyaih V i which it is'ieperaitedg"and rhaving ashmn: 3b W p pasi tien thefsi'iaftfi earryingethe short'ihi'trW "is moved'towardzthe heettrseleg: hysp ailing Vis -an; arm: (i i5 3 dea er: X, pivoted ate to theframe, the ether Y thetree legy half aniiiich, the distancerheing gagadhythe; ahnttingiof its portionagainstits bearing l. attithespring:zfilthenbieingailewed :tei-retnirn thefshaift to; its;normializpcsitien. pivoted arm: M: is than: swung down for its shcnlderlh teihe Ehel ow er: out of: the; way of an-clhitsiherneeessaryispeema 1 listed prnperly and then the iupperf-rame E,

This groove being cut the burring tool is then moved up out of the way by moving its handle H down, then the upper frame E is moved forward and in to its position on the carriage frame 0, which position is gaged by the abutment and stop ofthe frameE against a lug N" secured to the front side of carriage frame, as shown. in Figs. 1 and 3. This stop being secured and arranged so that the frame E, when bearing against it will be in proper position'for the boot tree to be properly presented to the long drill forit to bore the hole P in the tree leg in the right position. The carriage frame is then moved along the rails B, B, by turning-the gear J, by its handle K, in the direction of the arrow Fig. 1,when the bit P, entersthe hole made by the small or centering bitW and thecarriage being pressed along the rails the bit bores the holeP through the whole length of the tree leg and as the frame is so moved it pushes theguide support frame '11, for the bit along with it, so that the bit moved and another carefully adjusted and.

secured in place thereon and the carriages moved as before to saw the end, center the hole, burr the groove, and bore the hole in the tree and so on, one after another. As the hole through the tree must be at an anglein order that its inner end shall be atone side of its center and the outer end near its center, as is well known, the angle being shown in dotted lines, see Fig. 5, to secure this angle the frame A supporting carriage frame C is arranged at such angle while the tree leg is supported on the frame having its central longitudinal axial line in a horizontal line by which the long bit P, will bore the hole through the same at the required angle, the saws and other tools being arranged parallel and at right angles or substantially so to the longitudinal axial line of the tree leg. The short bit W is for the purpose of centering the end 8 of the tree where the socket in the leg is to be made, therefore it is parallel with the long boring bit or drill. To insure the placing of other tree legs of the same size and pattern to be operated upon and have them all alike each tree leg has a small headed pin or tack driven in to the pointside of the tree leg as shown at '1" Fig. 2, more particularly and when the tree leg is put in position it is placed so that the head of this pin or tack will be preferably under a downwardly projecting point a of an arm V, but as shown in the drawings it is at one side, to more clearly show it. This arm V is secured by slot 12 and set screw d to another arm N pivoted to a vertical stationary red A secured by set. nuts 13 to the back arm 0 of the frame E. The arm rests upon a collar D secured to the vertical rod A by a set screw e on which it can be moved up and down to adjust it to the desired height as different widths of tree legs are operated upon, and when properly adjusted secured by its set screw. The arm can be swung back out of the way when removing the tree leg as shown in dotted lines Fig. 2. The smaller arm V has on its edge gage marks f which can be arranged to ascale and numbered to set the arm at any desired point in relation to the end g of the arm VV'or any definite mark thereon, which then can be secured by the thumb screw, also when in position the arm can be made rigid by its set screwE To prevent the arm WV swinging too far to the left, see Fig. 2, and to always bring it into the same position vertically a pin it of the arm abuts against an upright pin m of the collar, as shown in plan in Fig. 8.

Having thus described my invention, what I claim is 1. In combination, a table or support provided with longitudinal guide rails, a frame adapted to move back and forth on said guide rails, transverse guide rails on the upper side of said frame at right angles to said guide rails, a frame adapted to move back and forth on said transverse rails, transverse guide rails on said table or support back of longitudinal rails and on the horizontal plane of the transverse rails on said frame and in position to form a continuation thereof, and means on said latter frame for supporting and securing a boot tree leg thereon, whereby said boot tree can be carried forward and backward and laterally for operation thereon by certain tools, one after the other.
